I played 3 of the 4 bosses because the last one wasn't loading in the title screen, also when i played the web version it had a very janky camera that when it shakes it went outside of the arena and didn't stop, aside of that the game was very interesting.
The most fun was trying the different powers, each one very unique, so much that I wanted to do combos with them but waiting for the next move made it not possible (also It kinda annoyed me that when you did the jump attack the character flew back almost always hitting some spikes).
Visually impressive even with the unique light effects and the amount of particles, everything had some reaction.
The music was awesome, very great for each boss fight even when it was difficult to hear some signs of the enemy.
My first experience was kinda frustrating due that camera bug, but aside of that is a pretty neat game.
